Nicholas Agar offers a more nuanced view of the transformative potential of genetic and cybernetic technologies, making a case for moderate human enhancement—improvements to attributes and abilities that do not significantly exceed what ...

While humans have made enormous progress in the exploration and exploitation of Earth, exploration of outer space remains beyond current human capabilities. The principal challenges lie in current space technology and engineering which includes the protection of astronauts from the hazards of working and living in the space environment. These challenges may lead to a paradoxical situation where progress in space technology and the ability to ensure acceptable risk/benefit for human space exploration becomes dissociated and the rate of (...) scientific discovery declines. In this paper, we discuss the predominant challenges of the space environment for human health and argue that development and deployment of a human enhancement policy, initially confined to astronauts – for the purpose of future human space programmes is a rational solution to these challenges.

The current use of the term ‘Human Enhancement’ implies that it is a modern, new phenomenon in which, for the first time in history, humans are able to break through their god or nature-given bodily limits thanks to the application of new technologies. The debate about the legitimation of ‘HE’, the selection of methods permitted, and the scope and purpose of these modern enhancement technologies has been dominated by ethical considerations, and has highlighted problems with the definition (...) of the relevant norms. For example, ‘HE’ always presupposes that the current state of the ‘natural human’ or ‘healthy’ body is defined in opposition to an ‘artificial human’ or ‘diseased or disabled’ body, and also desirable technologies and methods are not but should be defined on the basis of objective, universally accepted criteria. All these definitions are, however, linked to socio-cultural norms and ideals, which can vary over time and between cultures. It is therefore impossible to arrive at a universal, durable definition of ‘enhancement’ that can be shared and understood globally, and will remain permanently valid. This discussion note contrasts the terms ‘HE’ and ‘Body Modification’ , and their respective strengths and weaknesses. ‘BM’ is a neutral term that is capable of encompassing every kind of modification, be it cultural, physical, psychological or neurological, is not limited to certain techniques and is not reliant on normative sub-definitions . In the light of this analysis, it is proposed that the term ‘HE’ be replaced with ‘BM’ in order to allow a neutral, unprejudiced discussion to take place. (shrink)

Human enhancement technologies raise serious ethical questions about health practices no longer content simply to treat disease, but which now also propose to “optimize” human beings’ physical, cognitive and psychological abilities. These technologies call for a reassessment of our relationship to health, the human body and the body's organic, identity and social functions. In nursing, such considerations are in their infancy. In this paper, we argue for the relevance of critical phenomenology as a way to better (...) understand the ethical issues related to human enhancement technologies (HET). In so doing, we seek to problematize HET and assess their influence on the future development of nursing science and practice. It is difficult to anticipate the concrete effects of HET, we suggest, because these practices reconfigure the meaning of normativity and disorient our conventional ethical landscape. In this context, we argue that the later work of Martin Heidegger and Michel Foucault invites a critical perspective into how techno‐scientific discourses modify our relationship to care, to health and to our own social and corporeal identities. Despite the traditional philosophical opposition between phenomenology and critical theory, we maintain that a hybrid critical phenomenological approach opens new ways to assess the integration of technology and practice. Our analysis understands HET as a process of “hybridization” between technological objects and human subjects. Critical phenomenology thus effectively questions anthropocentric definitions of technology, challenges the dichotomy between curative treatment and enhancement and, finally, prompts valuable reflection on the implications of HET for nursing theory and practice.

Although dominated by consequentialist and deontological thinking, the debate about human enhancement has been enriched by several arguments from virtue theory and from virtue ethics. This article provides an overview of the virtue ethical arguments in the debate and identifies several topics in the ethics of human enhancement where the argumentative resources of virtue ethics have not yet been sufficiently considered.

The impact of "human enhancement" can manifest itself only overtime. And this is why, the author argues, "human enhancement" is an issue for the youth-oriented policies. As such, the problem of "human enhancement" is a social problem. The author stresses the influence of individual experiments that young people run on themselves and that have to do with human enhancement. He argues that these experiments have the potential of opening new directions for a (...) social construction of reality. He relates this potential to the innovative impulse that young people have.

Is it necessary to have an ideal of perfection in mind to identify and evaluate true biotechnological human “enhancements”, or can one do without? To answer this question we suggest employing the distinction between ideal and non-ideal theory, found in the debate in political philosophy about theories of justice: the distinctive views about whether one needs an idea of a perfectly just society or not when it comes to assessing the current situation and recommending steps to increase justice. In (...) this paper we argue that evaluating human enhancements from a non-ideal perspective has some serious shortcomings, which can be avoided when endorsing an ideal approach. Our argument starts from a definition of human enhancement as improvement, which can be understood in two ways. The first approach is backward-looking and assesses improvements with regard to a status quo ante. The second, a forward-looking approach, evaluates improvements with regard to their proximity to a goal or according to an ideal. After outlining the limitations of an exclusively backward-looking view, we answer possible objections against a forward-looking view. Ultimately, we argue that the human enhancement debate would lack some important moral insights if a forward-looking view of improvement is not taken into consideration. (shrink)

Human enhancement is ontologically, epistemologically, and ethically challenging and has stirred a wide range of scholarly and public debates. This article focuses on some conceptual issues with HE that have important ethical implications. In particular it scrutinizes how the concept of human enhancement relates to and challenges the concept of health. In order to do so, it addresses three specific questions: Q1. What do conceptions of HE say about health? Q2. Does HE challenge traditional conceptions of (...) health? Q3. Do concepts of health set limits to or direct HE? Addressing Q1 reveals that HE tends to frame and form our conception of health. Thereby it challenges traditional conceptions of health. Accordingly, health does not provide strong sources for setting limits to HE. On the contrary HE seems to define and expand the concept of health. Common to the concepts of HE and health is that both depend on vague value concepts, such as happiness, well-being, or goodness. There seems to be a tendency in the HE literature to define the goal of human life in terms of what is bigger, stronger, faster, more intelligent, and more resilient. However, this is confusing “goodness” with “more” and quality with quantity. Until HE more appropriately defines happiness, HE will fail to provide a relevant compass for improving the life of human beings. On the contrary, if we let simplified conceptions of “enhancement” come to define goodness or health, we may do more harm than good. Until doing so, we may well learn from Tithonus, listen to Douglas Adams’ Wowbagger, and pay attention to Virginia Woolf’s Orlando. Enhanced life may not be better. The same goes for health.

Bioethicists and philosophers dominate the on-going debate on human enhancement. They have debated the definition of human enhancement as well as the potential impacts of human enhancement technologies (such as pharmaceutical enhancements or pre-natal selection). These discussions have percolated, through bioethics bodies and bioethics recommendations, policy makers and have eventually been translated into policy. While some suggestions have been based largely in Western liberal democracies, others have deliberated the geopolitical consequences of human (...) class='Hi'>enhancement technologies. This paper argues that the present debate currently lacks perspectives from developing countries. It begins by introducing the current debate on human enhancement and recognizes Allen Buchanan’s well-raised concerns on how these technologies may potentially cause new injustices for low- and middle-income countries (‘developing countries’). It then provides two arguments calling for further research into human enhancement from the perspective of developing countries. First, this paper will argue that the current frames with which enhancement technologies are viewed are inherently neoliberal and require change. The second argument shows how the potential impacts of human enhancement technologies in developing countries have not been fully realized by analyzing how human enhancement technologies will impact Thailand, a developing country.

This paper affirms human enhancement in principle, but questions the inordinate attention paid to two particular forms of enhancement: life extension and raising IQ. The argument is not about whether these enhancements are possible or not; instead, I question the aspirations behind the denial of death and the stress on one particular type of intelligence: the logico-analytic. Death is a form of finitude, and finitude is a crucially defining part of human life. As for intelligence, Howard (...) Gardner and Daniel Goleman show us the importance of multiple intelligences. After clarifying the notion of different psychological types, the paper takes five specimens of a distinct type and then studies the traits of that type through their examples. Seeking a pattern connecting those traits, the paper finds them bound together by the embrace of the computational metaphor for human cognition and then argues that the computational metaphor does not do a good job of describing human intelligence. Enlisting the works of Jaron Lanier and Ellen Ullman, the paper ends with a caution against pushing human intelligence toward machine intelligence, and points toward the human potential movement as a possible ally and wise guide for the transhumanist movement.

Book review of the book Inquiring into Human Enhancement: Interdisciplinary and International Perspectives (2015), edited by Simone Bateman, Sylvie Allouche, Jean Gayon, Michela Marzano and Jérôme Goffette. Closing the summary of the book's chapters, the reviewer asks: when imagining HE for the future, especially in utopian directions, might we not seek to increase human wisdom, for instance, rather than just human intellect? Why are human enhancement visions so often limited by egotistical, if well-intended, desires (...) that might go horribly wrong, as in the story of Dr. Jekyll and Mr. Hyde? (shrink)

:This article explores some implications of the concept of transformative change for the debate about human enhancement. A transformative change is understood to be one that significantly alters the value an individual places on his or her experiences or achievements. The clearest examples of transformative change come from science fiction, but the concept can be illuminatingly applied to the enhancement debate. We argue that it helps to expose a threat from too much enhancement to many of (...) the things that make human lives valuable. Among the things threated by enhancement are our relationships with other human beings. The potential to lose these relationships provides a compelling reason for almost all humans to reject too much enhancement. (shrink)

We examine a set of debates in Practical Ethics commonly labeled “the ethics of human enhancement.” Our essay focuses on (1) conceptual concerns about the limits of legitimate health care—the treatment vs. enhancement distinction, (2) moral considerations about fairness, authenticity, and human nature that are common in discussing the use of medical technologies in competitive institutions like sports and academia, and (3) broader issues that pertain to science policy and the distribution and regulation of medical technologies.

Several authors have speculated that (1) the pharmaceutical, genetic or other technological enhancement of human mental capacities could result in the creation of beings with greater moral status than persons, and (2) the creation of such beings would harm ordinary, unenhanced humans, perhaps by reducing their immunity to permissible harm. These claims have been taken to ground moral objections to the unrestrained pursuit of human enhancement. In recent work, Allen Buchanan responds to these objections by questioning (...) both (1) and (2). I argue that Buchanan’s response fails. However, I then outline an alternative response. This response starts from the thought that, though moral status-increasing human enhancements might render ordinary, unenhanced humans less immune to permissible harm, they need not worsen the overall distribution of this immunity across beings. In the course of the argument I explore the relation between mental capacity and moral status and between moral status and immunity to permissible harm. (shrink)

Throughout history, human beings have worked on their personal enhancement. Not only improving the living conditions, but also trying to improve the moral behavior of people, usually through education. The Transhumanist proposal of moral enhancement promises to make us better and understands it as a duty, also because of the ethical challenges that present to us. In the following article we explore if that is possible and to what extent, taking into account that humans are agents.

The article deals with the philosophical and ethical implications of transhumanism and human enhancement techniques. It considers how enhancement and therapy are two different types of biomedical intervention. It then looks at the implementation of these ideas in the military sector. It analyses various standpoints and views on transhumanism, the benefits and risks of using newly acquired scientific knowledge to improve and alter naturally deficient human nature. The need for ethical reflection and argumentation is emphasized; new (...) scientific discoveries can dramatically change our experience of the world around us and may present a huge risk to mankind if left unchecked and not critically discussed. The article reflects on the dangers and risks of human enhancement and its possible consequences on the battlefield as well as the broader contexts and implications. The article also considers which criteria would be suitable to ensure beneficial and less controversial enhancements are carefully selected and to enable these to be distinguished from more dangerous practices that change the human body and/or mind. The aim is to consider and evaluate the possible benefits and risks of using enhancements for military purposes and to identify possible criteria for their justification and/or rejection. (shrink)

In this essay, I will investigate the implications of human enhancement for personal identity and assess likely social and ethical consequences of these changes. Human enhancement, also called human augmentation, is an emerging field within medicine and bioengineering that aims to develop technologies and techniques for overcoming current limitations of human cognitive and physical abilities (Naam, 2004; Wilsdon and Miller, 2006; Garreau, 2005; Parens, 1998; Agar, 2004). Technologies developed in this field are called (...) class='Hi'>human enhancement technologies (HETs). HETs rely on advances in genetic engineering, pharmacology, bioengineering, cybernetics and nanotechnology. In these fields, it is becoming possible to develop techniques that improve human functions beyond a normal range. The envisioned applications are limitless, and include the enhancement of human traits like muscular strength, endurance, vision, intelligence, mood and personality. (shrink)

Our technologies have enabled us to change both the world and our perceptions of the world, as well as to change ourselves and to find new ways to fulfil the human desire for improvement and for having new capacities. The debate around using technology for human enhancement has already raised many ethical concerns, however little research has been done in how human enhancement can affect human communication. The purpose of this paper is to explore (...) whether some human enhancements could change our shared lifeworld so radically that human communication as we know it would not be possible any longer. After exploring the kinds of communication problems we are concerned with as well as mentioning some possible enhancement interventions that could bring about such problems, we will address some of the ethical implications that follow from these potential communication problems. We argue that because of the role that communication plays in human society, this issue deserves attention. (shrink)

Debate concerning human enhancement often revolves around the question of whether there is a common “nature” that all human beings share and which is unwarrantedly violated by enhancing one’s capabilities beyond the “species-typical” norm. I explicate Thomas Aquinas’s influential theory of human nature, noting certain key traits commonly shared among human beings that define each as a “person” who possesses inviolable moral status. Understanding the specific qualities that define the nature of human persons, which (...) includes self-conscious awareness, capacity for intellective thought, and volitional autonomy, informs the ethical assessment of various forms of enhancement. Some forms of cognitive and physical enhancement may be desirable from the perspective of what constitutes the “flourishing” of human persons in our fundamental nature; while other forms of enhancement, such as emotive or so-called “moral” enhancement, run the risk of detracting from human flourishing when evaluated from the virtue-theoretic perspective Aquinas promotes.

Since before we can remember, humanity aims to overcome its biological limitations; such a goal has certainly played a key role in the advent of technique. However, despite the benefits that technique may bring, the people who make use of it will inevitably be under risk of harm. Even though human technical wisdom consists in attaining the best result without compromising anybody’s safety, misuses are always a possibility in the horizon. Nowadays, technology can be used for more than just (...) improving human capacities, preserving and restoring health or promoting human well-being. It also enables us to overcome human limitations and reach way beyond our "natural design". That being said, what could possibly justify the fear for these new directions of biotechnology? Should medicine and health care change their traditional goals and begin searching for artificial improvements to wellness in human nature? In this paper, I will hereby present and briefly discuss the main topics of the contemporary issue of human enhancement: the therapy-enhancement distinction, the possibility of cognitive enhancements and better physical performances, the fight against senescence, the arguments for and against human eugenics, the search for perfection, the quest of moral enhancement, the problem of public priorities, and some questions on medical ethics. Then, finally, I will want to present some realist perspectives on the subject. (shrink)

The past few years has seen a resurgence in the public interest in space flight and travel. Spurred mainly by the likes of technology billionaires like Elon Musk and Jeff Bezos, the topic poses both unique scientific as well as ethical challenges. This paper looks at the concept of generation ships, conceptual behemoth ships whose goal is to bring a group of human settlers to distant exoplanets. These ships are designed to host multiple generations of people who will be (...) born, live, and die on these ships long before it reaches its destination. This paper takes reproductive ethics as its lens to look at how genetic enhancement interventions can and should be used not only to ensure that future generations of offspring on the ships, and eventual exoplanet colonies, live a minimally good life but that their births are contingent on them living genuinely good and fulfilling lives. The paper makes the further claim that if such a thesis holds, it also does so for human enhancement on Earth. (shrink)

I argue that the existence of sexual dimorphism poses a profound challenge to those philosophers who wish to deny the moral significance of the idea of ‘normal human capacities’ in debates about the ethics of human enhancement. The biological sex of a child will make a much greater difference to their life prospects than many of the genetic variations that the philosophical and bioethical literature has previously been concerned with. It seems, then, that bioethicists should have something (...) to say about the choice between a male and a female embryo. Either, 1) parents have reason to choose boys over girls; (2) parents have reason to choose girls over boys; or, (3) parents have neither reason to choose girls over boys nor reason to choose boys over girls. Embracing either of the first two alternatives has strongly counterintuitive – and arguably morally repugnant – consequences. To motivate the third option we must either make reference to the idea of ‘normal human capacities’ or argue that parents should consider the interests of society when thinking about what sort of children they should bring into the world – an implication that should be extremely controversial in debates about the ‘new eugenics’. I conclude, then, that the idea of ‘normal human capacities’ is properly crucial to reasoning about the ethics of shaping future persons. (shrink)

Human enhancement—the attempt to overcome all human cognitive, emotional, and physical limitations using current technological developments—has been said to pose the most fundamental social and political question facing the world in the twenty-first century. Yet, the public remains ill prepared to deal with it. Indeed, controversy continues to swirl around human enhancement even among the very best-informed experts in the most relevant fields, with no end in sight. Why the ongoing stalemate in the discussion? I (...) attempt to explain the central features of the human enhancement debate and the empirical and normative shortcomings that help to keep it going. I argue that philosophers of science are especially well equipped to rectify these shortcomings, and I suggest that we may be deeply remiss if we don’t do so. (shrink)

To what extent should we use technological advances to try to make better human beings? Leading philosophers debate the possibility of enhancing human cognition, mood, personality, and physical performance, and controlling aging. Would this take us beyond the bounds of human nature? These are questions that need to be answered now.

During the last congress of the International Association of Bioethics in Beijing, there was a special session on human enhancement. John Harris, pioneer in the discussions on the ethics of enhancement,1 summarised this session, describing the focus of different panelists.2 This session included: Biopsychological enhancements The possibility of regulating emotions through pharmacological means Biases that may affect our judgments against human enhancement Health care inequalities that will follow from the adoption of genetic technology Social impact (...) and costs of adopting the new technology A discussion on women enhancing their physical strength as men through genetic modification .The Beijing panel did not address women’s involvement in the enhancement scenario. Of course, not every aspect of a topic can be covered in one session of a congress and some aspects may remain unaddressed; mainly, because these sessions draw from the research interests of the presenters. However, neither John Harris nor Julian Savulescu has yet addressed women’s crucial involvement in the enhancement scenario. It is the aim of this paper to draw attention to the invisibility of the ‘vessel’ in these discussions. Enhancement may be justified; but clearly, it will also affect women. In this scenario, will women be worse off?LATE ONSET DISEASES AND ENHANCEMENTFirstly, I would like to point out that I believe that enhancement may be a necessary step in the future of human evolution. As I have explained elsewhere,3 health care systems in the developed world are near to collapse under the pressure of late onset chronic diseases. Largely successful in preventing early deaths in the last century, health care systems have prompted a new plague, recognised lately by the World Health Organization as a new pandemic …. (shrink)

About one and a half decades ago, two prominent reports were published in the United States which strongly influenced subsequent international discussions on the topic of human enhancement: a 2002 report on “converging technologies for improving human performance”, based on a workshop which was organised by the US National Science Foundation and the US Department of Commerce in December 2001, and the first report of US President George W. Bush’s Council on Bioethics, published in October 2003 with (...) the title Beyond Therapy: Biotechnology and the Pursuit of Happiness. The 2002 report included a wide variety of contributions from academics in various fields of research, from representatives of US institutions, and from companies. Due primarily to the influence of the two NSF staff editing the report, it can be regarded as the first major instance of the influence of transhumanism, a techno-futurist ideology and movement, on the US technology and innovation discourse. The PCBE report, on the other hand, is a prime example of a conservative critique of the transhumanist notion of human enhancement. In this invited contribution, these two crucial publications are analysed mainly in order to point out the relevance of philosophical anthropology as developed since the 1920s by Helmuth Plessner and others. This remarkable school of thought is experiencing a revival in countries such as Germany and the Netherlands, and, to some extent, in the English-speaking world. In this article, it is argued that philosophical anthropology provides us with an important alternative to both anthropological essentialism and scientism, two approaches that are still highly relevant in current discourse on human enhancement.

Several philosophers have argued that human enhancements should be considered a potential solution to climate change. In this paper, I consider one such argument offered by S. Matthew Liao, Anders Sandberg, and Rebecca Roache. I argue that, while their argument is plausible, we have an even stronger reason to consider enhancements a potential solution. In particular, enhancements could align our interests with the promotion of a proper response to climate change: if enhancements were in our interest to adopt and (...) also reduced the pernicious effects of climate change, then it would, indirectly, become in our interest to reduce those effects.

Human enhancement, in which nanotechnology is expected to play a major role, continues to be a highly contentious ethical debate, with experts on both sides calling it the single most important issue facing science and society in this brave, new century. This paper is a broad introduction to the symposium herein that explores a range of perspectives related to that debate. We will discuss what human enhancement is and its apparent contrast to therapy; and we will (...) begin to tease apart the myriad intertwined issues that arise in the debate: (1) freedom & autonomy, (2) health & safety, (3) fairness & equity, (4) societal disruption, and (5) human dignity.

Improving human characteristics goes beyond compensating for an impairment. This book explores the rich and complex relationship between enhancement and impairment, showing that the study of disability offers new ways of thinking about the social and ethical implications of improving the human condition.

The expression “human enhancement” could be placed in the ontological, cognitive, and symbolic dimension in which we conceive and experience the faculty, that is constitutive of human beings, of giving name and thus consistence to things, relations and phenomena in general. It is necessary to point out that this symbolic dimension of emerging technologies has been obstinately and jealously anthropocentric, at least in the modern Western world. In this contribution, I aim to develop a philosophical account of (...) post-human enhancement that allows us to conceive a future society of humanoids – humans, hybrids, artificial beings – who are free and equal. This expression – “post-human enhancement” – is to be understood as referring to symbols and phenomena different from those associated with “trans-human”. Post-human is to be interpreted here as material, not anthropocentric but rather interspeciesist, osmotic and relational, horizon of effective sharing of experiences, dangers and challenges. In contrast, trans-human is meant to refer to the transcending of humans into the pure ether of an ‘ideal’, immaterial network made up only of software, and lacking of relations with any material beings in the ecosystem or cosmos. On my account, reframing the debate about human enhancement means to guarantee widest possible conditions of non-hegemonic or expansive conscious contextuality of legislative and decisional systems. I focus rather on the social circumstance whereby we see ourselves as subjects that already co-inhabit multiform social identities, in changeable and hybrid bodies and identitary images, in potential or latent conditions of moral and political asymmetry. These conditions, I hold, are therefore to be preventively identified and neutralized. (shrink)

This article critically evaluates bettering human life. Because this involves lives that do not exist yet, the article investigates human eugenics and enhancement through the social prism of ‘the imaginary’ (defined ‘as a set of assumptions and concepts for thinking and speaking about human enhancement and its future direction’) [1]. “Exploring basic assumptions underlying the idea of human enhancement” investigates underlying assumptions and claims for human enhancement. Firstly, human eugenics and (...) enhancement entangles a factual as well as a normative claim about what improvement/betterment maybe constitutive of. Secondly, claims about what a better life is, is often a future orientated claim about whether certain kinds of life that do not exist yet should ever exist. Moral images of thought are introduced and how they work to make normative judgments about lives that do not exist. This implicates the moral problem of difference, where an image of a ‘better’ life—classically expressed in eugenics as a ‘superior’ and/or ‘normal’ life—necessarily entails inferiority and/or deviance from a norm. “Moral imagination in contemporary fiction and the history of old eugenics”, introduces moral images in history of eugenics and demonstrates how examples fall foul of the problem. “The new (liberal) eugenics and the moral image of therapy” examines progress in contemporary debates, the move from authoritarian to non-authoritarian eugenics (human enhancement), and how, to some extent, this has solved the problem of difference, through liberal defence of personal choice. “The heart of the eugenic issue” suggests that personal choice in liberal non-authoritarian eugenics is not immune to basic drive behind all eugenic arguments; desire as lack which is expressed as the continual dissatisfaction of not having our future expectations met.

Ethical debate surrounding human enhancement, especially by biotechnological means, has burgeoned since the turn of the century. Issues discussed include whether specific types of enhancement are permissible or even obligatory, whether they are likely to produce a net good for individuals and for society, and whether there is something intrinsically wrong in playing God with human nature. We characterize the main camps on the issue, identifying three main positions: permissive, restrictive and conservative positions. We present the (...) major sub-debates and lines of argument from each camp. The review also gives a flavor of the general approach of key writers in the literature such as Julian Savulescu, Nick Bostrom, Michael Sandel, and Leon Kass. (shrink)

Michael Sandel's opposition to the project of human enhancement is based on an argument that centres on the notion of giftedness. Sandel claims that by trying to ?make better people? we fall prey to, and encourage, an attitude of mastery and thus lose, or diminish, our appreciation of the giftedness of life. Sandel's position and the underlying argument have been much criticised. In this paper I will try to make sense of Sandel's reasoning and give an account of (...) giftedness that defends its relevance for the ethical assessment of the human enhancement project. In order to do so, I will also look at virtue-related notions, such as gratitude and humility, and distinguish the gifted from the merely given. The failure to acknowledge this distinction gives rise to one of the most common objections to Sandel's argument. Other objections will be shown to rest on similar misunderstandings. (shrink)

In an intriguing essay, G. A. Cohen has defended a conservative bias in favour of existing value. In this paper, we consider whether Cohen’s conservatism raises a new challenge to the use of human enhancement technologies. We develop some of Cohen’s suggestive remarks into a new line of argument against human enhancement that, we believe, is in several ways superior to existing objections. However, we shall argue that on closer inspection, Cohen’s conservatism fails to offer grounds (...) for a strong sweeping objection to enhancement, and may even offer positive support for forms of enhancement that preserve valuable features of human beings. Nevertheless, we concede that Cohen’s arguments may suggest some plausible and important constraints on the modality of legitimate and desirable enhancements. (shrink)

Essay I explores brain machine interface technologies. These make direct communication between the brain and a machine possible by means of electrical stimuli. This essay reviews the existing and emerging technologies in this field and offers an inquiry into the ethical problems that are likely to emerge. Essay II, co-written with professor Sven-Ove Hansson, presents a novel procedure to engage the public in deliberations on the potential impacts of technology. This procedure, convergence seminar, is a form of scenario-based discussion that (...) is founded on the idea of hypothetical retrospection. The theoretical background and the results of the five seminars are presented. Essay III discusses moral bioenhancement, an instance of human enhancement that alters a person’s dispositions, emotions or behavior. Moral bioenhancement could be carried out in three different ways. The first strategy is behavioral enhancement. The second strategy, favored by prominent defenders of moral enhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I argue that we ought to implement a combination of the second and third strategies. Essay IV considers the possibility and potential desirability of sensory enhancement. It is proposed that existing sensory modalities in vertebrate animals are proof of concept of what is biologically possible to create in humans. Three considerations on the normative aspects of sensory enhancement are also presented in this essay. Essay V rejects disease prioritarianism, the idea that the healthcare system ought to prioritize the treatment of diseases. Instead, an approach that focuses on what medicine can accomplish is proposed. Essay VI argues that from the idea that species have an intrinsic value and that humanity has a collective responsibility to protect animal species from extinction, the conclusion that we ought to recreate species follows. Essay VII argues that unknown existential risks have not been properly addressed. It proposes a heuristic for doing so, and a concrete strategy. This strategy consists in building refuges that could withstand a large number of catastrophic events. (shrink)

There are various aspects of the debate on human enhancements that frustrate the possibility of reaching consensus on their value, and I will focus on two of the more crucial obstacles: (a) the need to rationalize medical resources and (b) the concern that such use would be the first step on a “slippery slope” to some undesirable end. Respectively, the decision to permit unfettered access to enhancements relies on being able to devote resources to such modifications and attending to (...) the concern that such access would not lead to the collapse of healthcare or generally making society worse off.

For most theologians, theology should ultimately be used by the laity and/or the public. However, the religion and science debate has not focused on the divide between theologians and the laity. In this case study I examine the debate among theologians about human enhancement. I focus on the extent to which the structure of the debate in a “mediating organization” between the theologians and the public coincides with the structure of the debate among the theologians. I conduct a (...) survey of participants in the organization, and find that the basic divides among the theologians are largely replicated. These results, when combined with studies of the theologians themselves and the laity, provide a more holistic understanding of the future debate about human enhancement. (shrink)

Both, bioconservatives and bioliberals, should seek a discussion about ideas of human perfection, making explicit their underlying assumptions about what makes for a good human life. This is relevant, because these basic, and often implicit ideas, inform and influence judgements and choices about human enhancement interventions. Both neglect, and polemical but inconsistent use of the complex ideas of perfection are leading to confusion within the ethical debate about human enhancement interventions, that can be avoided (...) by tackling the notion of perfection directly. In the recent debates, bioconservatives have prominently argued against the ‘pursuit of perfection’ by biotechnological means. In the first part of this paper, we show that—paradoxically—bioconservatives themselves explicitly embrace specific conceptions of human perfection and perfectionist assumptions about the good human life in order to argue against the use of enhancement technologies. Yet, we argue that the bioconservative position contains an untenable ambiguity between criticising and endorsing ideas of human perfection. Hence, they stand in need of clarifying their stance on human perfection. In the second part of the paper, we ask whether bioliberals in fact (implicitly) advocate a particular conception of perfection, or whether they are right in holding that they do not, and that discussing perfection is obsolete anyway. We show that bioliberals also rely on a specific idea of human perfection, based on the idea of autonomy. Hence, their denial of the relevance of perfection in the debate is unconvincing and has to be revised. (shrink)

This paper tries to clarify, strengthen and respond to two prominent objections to the development and use of human enhancement technologies. Both objections express concerns about the link between enhancement and the drive for hyperagency. The first derives from the work of Sandel and Hauskeller—and is concerned with the negative impact of hyperagency on social solidarity. In responding to their objection, I argue that although social solidarity is valuable, there is a danger in overestimating its value and (...) in neglecting some obvious ways in which the enhancement project can be planned so as to avoid its degradation. The second objection, though common to several writers, has been most directly asserted by Saskia Nagel, and is concerned with the impact of hyperagency on the burden and distribution of responsibility. Though this is an intriguing objection, I argue that not enough has been done to explain why this is morally problematic. I try to correct for this flaw before offering a variety of strategies for dealing with the problems raised. (shrink)

Emerging technologies are increasingly used in an attempt to “enhance the human body and/or mind” beyond the contemporary standards that characterize human beings. Yet, such standards are deeply controversial and it is not an easy task to determine whether the application of a given technology to an individual and its outcome can be defined as a human enhancement or not. Despite much debate on its potential or actual ethical and social impacts, human enhancement is (...) not subject to any consensual definition. This paper proposes a timely and much needed examination of the various definitions found in the literature. We classify these definitions into four main categories: the implicit approach, the therapy-enhancement distinction, the improvement of general human capacities and the increase of well-being. After commenting on these different approaches and their limitations, we propose a definition of human enhancement that focuses on individual perceptions. While acknowledging that a definition that mainly depends on personal and subjective individual perceptions raises many challenges, we suggest that a comprehensive approach to define human enhancement could constitute a useful premise to appropriately address the complexity of the ethical and social issues it generates.

We humans can enhance some of our mental and physical abilities above the normal upper limits for our species with the use of particular drug therapies and medical procedures. We will be able to enhance many more of our abilities in more ways in the near future. Some commentators have welcomed the prospect of wide use of human enhancement technologies, while others have viewed it with alarm, and have made clear that they find human enhancement morally (...) objectionable. The Ethics of Human Enhancement examines whether the reactions can be supported by articulated philosophical reasoning, or perhaps explained in terms of psychological influences on moral reasoning. An international team of ethicists refresh the debate with new ideas and arguments, making connections with scientific research and with related issues in moral philosophy. (shrink)
